subview

A Container View can be easily added into a storyboard through Interface Editor. When added, a Container View is of a placeholder view, an embed segue, and a (child) view controller. However, I am not able to find a way to add a Container View programmatically. Actually, I am not even able to find a class named UIContainerView or so. A name for the class of Container View is surely a good start. A complete guide including the segue will be much appreciated. I am aware of View Controller Programming Guide, but I do not regard it as the same as the way Interface Builder does for Container Viewer

I'm struggling with this problem! I want to add a google maps GMSMapView into a UIView that is only a portion of the main UIView of my ViewController . It should be simple... I created with the storyboard a UIView of the size I want and put it in the main UIView . Snippet from Interface file: @interface MapViewController : UIViewController <CLLocationManagerDelegate> @property(nonatomic) IBOutlet GMSMapView *mapView; With the mapView linked with this UIView inside the main UIView . What I do in the implementation: @synthesize mapView = _mapView; - (void)viewDidLoad { [super viewDidLoad]; // Do

I created UIImageView with the help of Interface Bulder. Now I want to place label inside it (as its subview). In code I can type something like: [myUIImageView addSubview:myUILabel]; But can I do it with the help of IB? I found the solution for UIView , but can't find something similar for UIImageView . You cannot add a subview to UIImageView in interface builder for reasons only known to Apple! You are right in saying that you can addSubview programmatically, but then, the overhead of setting autoresizing masks and placements of subviews should all be handled in code, which is cumbersome. So

When my app gets back to its root view controller, in the viewDidAppear: method I need to remove all subviews. How can I do this? e.James Edit: With thanks to cocoafan : This situation is muddled up by the fact that NSView and UIView handle things differently. For NSView (desktop Mac development only), you can simply use the following: [someNSView setSubviews:[NSArray array]]; For UIView (iOS development only), you can safely use makeObjectsPerformSelector: because the subviews property will return a copy of the array of subviews: [[someUIView subviews] makeObjectsPerformSelector:@selector

How can I loop through all subviews of a UIView, and their subviews and their subviews? Use recursion: // UIView+HierarchyLogging.h @interface UIView (ViewHierarchyLogging) - (void)logViewHierarchy; @end // UIView+HierarchyLogging.m @implementation UIView (ViewHierarchyLogging) - (void)logViewHierarchy { NSLog(@"%@", self); for (UIView *subview in self.subviews) { [subview logViewHierarchy]; } } @end // In your implementation [myView logViewHierarchy]; RamaKrishna Chunduri Well here is my solution using recursion and a wrapper(category/extension) for the UIView class. // UIView+viewRecursion.h
